Note: A "rough spot" in the context of graphite electrodes refers to an irregular or uneven surface area on the electrode, which can negatively affect its performance during use, particularly in electric arc furnaces. These spots can lead to increased wear, inconsistent electrical conductivity, and may contribute to the formation of defects in the molten steel.
Do not stack electrodes and connectors directly on the ground. Instead, place them on wooden or metal racks to prevent damage or contamination from soil. Do not discard the packaging of unused electrodes temporarily, as the packaging effectively prevents dust and debris from settling on the electrode surface or threads.
Graphite electrodes should be stored neatly in the warehouse, with both sides of the electrode stacks leveled to prevent sliding. The stacking height of the electrodes should generally not exceed 2 meters and preferably not exceed 4 layers.
Graphite electrodes should be protected from rainwater and moisture. If the electrodes become damp, they should be dried before use to prevent cracking, spalling, and increased oxidation consumption during the steelmaking process.
Do not store electrode nipple joints in high-temperature environments to prevent the melting of joint bolts due to excessively high temperatures.
